SAW sn'r. AND GAGE;

- Application and April 25,

To all whom it may concern: v

Be it known that I, BENJAMIN Bonnnrs,

a subject of the King of Great Britain, re-

' siding at Lake Saskatoon, in the Province of Alberta, Dominion ofCanada, have invented certain new and useful Improve-j ments in Saw Setsand Gages, of which the following is a specification.

This invention relates generally to tools, and particularly toinstruments adapted to be 11. ed in the repair or setting of saws,aiming primarily to provide a combined saw-set and gage, improved meansfor holding a file to operate upon the saw teeth in the adjusting ortrying of the latter, im proved means for gaging raker teeth, as well asthe embodiment of other elements for performing different functions.

further object of the invention is to provide a tool of this characterwherein a pair ofpivoted handle or jaw members are employed, the saidhandle members being provided with cooperating serrated faces to'e'lfecta pipe or nut gripping in strument, and means on one of the handleswhereby bolt threads may be cleaned or trued. U

A still further object of the .inventionis toprovide a tool or implementof this char acter, which is simple in construction, which, isinexpensive in manufacture, which is composed of few readily assembledparts,

the said parts being so arranged and con-.5

nected as to provide a powerful instrument and one which will notreadily becomebroken or damaged and which will prove thoroughlyeflicient in performing the functions for which it is designed.

Vith these objects in view, together with others which will appear asthe description proceeds, the invention resides in the novel formation,combination and arrangement of parts, all as will be described morefully hereinafter, illustrated in the drawings, and particularly pointedout in the claims.

The invention will be best understood by reference to the accompanyingdrawings, therein Figure 1 is an end view of a tool constructed andarranged in accordance with my invention;

The opposite or cooperating handle member 6i sprovided at one extremity with a disk or hammer portion 8, the latterbeing pivoted eccentrically as at ,9 between the furcations oftheangularly extending portion 7 of the handle 5. This hammer 8 is ofsubstantially' the same thickness at its point of pivotal connectionwith the member 5v as the distance between the furcations thereof,

annular edge so that the thickness of the hammer is materially reduced.The handlev 6, when swung inwardly will rock upon the pivot 9 and thehammer 8 will move 1n-v wardly int-o closelproximity to the straightportion of the handle member 5;

while its sides taper toward the outer An anvil 10' is extended throughthe I slotted or bifurcated end of the handlepoi tion 5, and consistsofa set screw which is provided with looking nuts 11 to maintain thesaid set screw in adjusted position within' the said slotted end. Theinner extremity of the anvil is: adapted to impinge a sawfblade duringthe setting operation of the tool to hold the latter while the hammer.

8 operates to properly incline or set the teeth thereof. A gage screw 12extends througha suitlble opening formed in the handle 6 substantiallyintermediate the ends of the latter. This gage screw is also pros videdwith looking nuts 13, the arrangement enabling the gage screw to bereadily adjusted through the said handle in amanner similar to that ofthe anvil 10. The gage screw 12 is adapted to be adjusted in such amanner as to bear against the outer or metal portion of the saw bladewhen the tool is adjusted to the saw to position the tance as the sameis out tool properly prior to the setting operation of the same.

By inclining the side faces of the disk portion 8 to present arelatively narrow outer edge, it is apparent that the device is capableof being readily used upon saws having teeth varying in width.

The inner face of the handle member 6 is notched at 14 adjacent thejuncture of the hammer 8 with the handle member. This notch providesangular walls, the latter being spaced apart a distance sufficient toaccommodate the edge of the ordinary fiat file. hen a file is placedwithin the grooves and the handles 5 and 6 swung together, the said filewill be firmly maintained in proper po-' sition to be passed over theteeth of a saw to properly aline the cutting ends or apices thereof. Thefile may, moved when required but during the filing operation, the saidfile will be firmly held in proper position.

In order that the tool may be efiiciently used with various types ofsaws, the handle 6 is bent at one edge to provide a longitudinallydisposed channel or groove 15, the said groove being of a widthsufiioient to accommodate relatively heavy saws. This groove extendsthroughout substantially one half the length of the handle portion 6 andthe said handle is cut away at its turned edge to provide a slot 16communicating with the interior of the channel 15. Intruing andsharpening saws of the raker type, the handle 6 of the tool ispositioned over the saw teeth with the raker teeth projecting throughthe slot 16. As the cutting teeth upon each side of the raker toothengage with the bottom of the channel 15, the said raker tooth will healined with the slot, and will intrude through the same such disofcutting alinement with the cutting teeth of the saw. Itis thus seen thatan effective for evening the raker teeth is provided. The extremity ofthe handle member 6 may be pointed or flattened as at 17 to provide ascrew driver.

The opposite handle 5 has arranged therein, a pluralitv of internallythreaded openings 18, the'latter varying in diameter, and are adapted tobe used to clean and even the threads or screw bolts by rotating thelatter in said openings.

7 have provided a tool which is with facility, be re The free extremityof the handle member 5 is crotched to provide a tack lifter or puller19.

To enable the tool to be used as a pipe or nut wrench, the adjacentfaces of the handle members 5 and 6 are serrated as shown and providegripping teeth 20, the latter being relatively sharp to insure a firmgrip upon the material with which the device is used.

It is obvious from this description that I of extremely simpleinexpensive construction, and which may be efiiciently used in theperforming of a number of functions. The readiness with which thevarious parts of. the device may be adjusted enables the tool to bereadily adapted to its various uses.

While the above is a description of the preferred embodiment of theinvention, it is apparent that various changes in the minor details ofconstruction and arrange ment of parts may be resorted to withoutdeparting from the spirit of the invention or exceeding the scope of theclaims.

Vhat is claimed is 1. A saw set and gage including two handles one ofwhich has its working end turned at right angles and slotted, a screwarranged through said handle and projecting beyond the walls thereof toprovide an anvil, the opposite handle having its working end flattenedand eccentrically pivoted in the slotted end of the opposite handle tocapacitate as a hammer to impinge the saw teeth and force them againstthe anvil.

2. A saw set and gage including a pair of handles one of which has itsworking end turned at right angles, a screw arranged through said handleand projecting beyond the walls thereof to provide an anvil, theopposite handle having its working end fiattened and eccentricallypivoted in the right angle portion of the opposite handle to capacitateas a hammer for coaction with the anvil, and a screw arrangedintermediately in one of the handles to impinge the saw blade andoperate as a gage.

In testimony whereof I aflix my signature in presence of two witnesses.

BENJAMIN ROBERTS.
